Our two year-old’s grandmother, grandma, gran and nana number four. As do grandfather, granddaddy, grampa and grandpop. So how best to differentiate between multiple male grandparents?

Exhaustive research revealed traditional alternatives including Big Daddy, Big Paw, Bumpy and Boppa. Thoroughly modern alternatives included all manner of elder titles from Ace and Boss to Rocky and Skipper.

Popular Poppy and Gramps meanwhile could respectively be too easily modified into Poopy and Grumps. Foreign language variations on this theme were similarly fraught with difficulties.

French Canadian Pépé had an air of animated malodorous skunk about it. Hawaiian Tutu Kane sounded, well, more like a mummy. Dead one at that.

Chinese YehYeh smacked of American indie rock band. Italian Nonno was non-starter. So we collectively plumped for GPP. For Grand Papa Pago.

Initially, learning formative vocabulary, she could only get her tiny tongue around last two initials.

Now Ella can articulate the entire acronym. Indeed, she can now say “Galapagos”. But she resolutely chooses not to.

Instead she takes great delight in mischievously calling “PP” at any given opportunity. Across the road. Around the park. Among the aisles. Anywhere. And any time.

Which is just fine by me, welcoming it as unique and endearing badge of honour. But one that can cause continual kerfuffle during current toilet training!
